First ride 30x10x14 Roctane did very well at Royal Blue TN . We had a lot of muddy conditions, and plenty of rocks and tree roots. Was in 2 wheel drive most of the time, very impressed with the tires, was running 8 psi in the rear and 6 psi in the front.Read All Reviews

We have an off-road tour company with a fleet of 14 UTVs. We have used just about every tire out there and these tires are the worst we have ever used. We put them on the front of a few of our UTVs and we wore through the tread in less than 2 months. Very disappointing and we do not recommend buying this tire unless you are always running in soft ground.Read All Reviews

These tires seem to hook up very well on semi hard pack terrain, however they loose a lot of traction in deep/ soft sand. They are very light and have a good resistance to punctures due to the 4 ply design. The tread seems to last very well and clean out mud. The cornering is very smooth and they give you a controlled slide around corners on a mx track. They are a low cost tire but they work just as good as a more expensive mx tireRead All Reviews
